The Tahoe Daily Tribune | Joanne Marchetta, Tahoe Regional Planning Agency | May 22, 2019

While it felt like spring had finally arrived, we all know Mother Nature can be fickle, especially at Lake Tahoe.

For those who love to play in the snow, it was a fantastic winter, and a banner year for the Sierra snowpack. Despite some cooler weather now, steady warmer temperatures are on the way and our attention is shifting from the mountains to the lake.

Boating season is here, and our ongoing battle in the fight against aquatic invasive species continues. For 11 years, more than 40 agencies and private nonprofit partners have worked to prevent the further spread of aquatic invasives.

The Tahoe Regional Planning Agency and our partners at the Tahoe Resource Conservation District are operating boat inspection stations around the basin. To date, we have been successful in this critical program. No discoveries of new aquatic invasive species have been detected over the last 10 years.

In no small measure, that’s thanks to the engagement of the boating community. Mandatory inspections have so far stopped the spread of aquatic invasive species like quagga and zebra mussels from entering Tahoe’s waters.

The mantra is simple: clean, drain, dry. Everyone launching a vessel at Lake Tahoe, whether it’s motorized or muscle powered, should be proactive in cleaning watercraft thoroughly. Once you clean it, make sure it’s drained and then fully dry before setting out. Research has shown that adult zebra mussels can survive for days out of water.

During the 2018 boating season, inspectors examined some 8,000 watercraft. Forty-four percent of those had been cleaned, drained and dried. But that means 56% of boaters and their vessels arrived at inspection stations with the potential to spread aquatic invasive species to Tahoe’s waters.

Were either of these invasive mussels able to take hold in Tahoe’s waters, their impacts could be catastrophic. Invasive mussels starve native aquatic species of nutrients they need to survive. Both quagga and zebra mussels are prolific procreators, quickly accumulating on underwater surfaces, encrusting docks, boats, and buoys. Their razor-like shells can carpet shallow waters and beaches, making for a painful encounter with the human foot.

There are harrowing examples of what could have been. Last July, Tahoe Resource Conservation District inspectors intercepted a boat infested with multiple aquatic invasive species. An undetected crack in the boat’s pontoon was allowing water to seep in. Inspectors found adult quagga and zebra mussels, and other aquatic plants and snails — a glaring example of how easy it is for an unsuspecting boater to introduce aquatic invasive species to Tahoe’s ecosystem.

While powerboats get most of the attention, local kayakers, paddle boarders, and other non-motorized watercraft users can also unintentionally introduce invasives to the lake. The League to Save Lake Tahoe’s “Eyes on the Lake” program has educated thousands of lake lovers, enlisting an army of citizen scientists to help monitor the lake’s shoreline and report sightings of invasive plants like watermilfoil and curlyleaf pondweed.

The League will offer several “Eyes on the Lake” training classes throughout the summer. Already, 3,000 people have been trained to keep an eye on Tahoe, helping to protect our clear and pristine waters. The Tahoe Keepers program also has enlisted thousands of paddlers in the quest to protect the lake.

Ground zero in the fight against invasive plants is the Tahoe Keys. The area continues to see large-scale infestations of invasive plants so severe that it’s threatening the entire lake.

In a genuinely collaborative undertaking, the Tahoe Keys Property Owners Association (TKPOA) has partnered with multiple organizations to develop a comprehensive plan to stop the spread of invasive plants. Last month, the property association provided the Tahoe Regional Planning Agency’s Governing Board with an update on the testing to be done in the Tahoe Keys over the next two years.

Testbed studies will be undertaken, using a variety of methods, including the continued application of underwater barriers and the testing of ultraviolet light treatments. The question of whether to use EPA-approved aquatic herbicides is still under discussion and review as part of the testing process over the next few years.

In the meantime, TKPOA and its partners are taking proactive measures to contain these invasive plants within the Keys’ borders. For a second summer, a bubble curtain will operate at the entrance to the Keys. Using a powerful stream of air, this curtain technology dislodges pieces of plant material attached to the bottom of watercraft. Pairing with the bubble curtains, TKPOA has also invested in autonomous sea bins to gather the plant material dislodged from boats leaving the marina.

Protecting and preserving Lake Tahoe’s waters is paramount to TRPA’s mission. Stopping the spread of aquatic invasive species at the lake is a daunting task, and collaborative actions will continue to pave the path to success.

Locations of watercraft inspection stations opening for summer season around the Lake Tahoe Basin.

 

 

The watercraft inspection program is entering its second decade of fighting aquatic invasive species at Lake Tahoe. The first 10 years were successful because of partnerships and support from the community, with no new documented invasions since the inception of the program.

“We are grateful to everyone who supports protecting Lake Tahoe from invasive species, especially the dedication and diligence of the Tahoe Resource Conservation District’s boat inspectors,” said Dennis Zabaglo, Tahoe Regional Planning Agency’s aquatic resources program manager.

All motorized watercraft require an inspection before launching into Lake Tahoe, Fallen Leaf Lake, Echo Lake, and Donner Lake. Invasive species, such as quagga mussels, New Zealand mudsnails, and hydrilla, are known to quickly colonize underwater surfaces. Knowingly transporting aquatic invasive species into Lake Tahoe is against the law, and violators are subject to fines.

This year, the annual watercraft inspection fee schedule is being simplified, condensing 13 categories to five to make it easier to understand and more accurately reflect inspection work and boat complexity. Decontamination fees were also modified to reflect the work it takes to decontaminate watercraft. To find out how the new fee schedule affects you, please visit:  tahoeboatinspections.com

Remember, before arriving at inspections stations: Clean, Drain, and Dry your watercraft. “Save time and money by making sure to drain all water from the intake systems, clean out your vessel, and make sure it is dry,” advises Chris Kilian, AIS program manager for the Tahoe Resource Conservation District.

Transporting boats on roads in the Lake Tahoe Basin and the state of Nevada requires bilge plugs to be removed from the vessel. Draining watercraft during transit helps prevent the spread of aquatic invasive species. Boaters on the water should fill and drain ballast tanks in the same location, making sure they are at least 200 feet from shore.

Invasive species are highly opportunistic, and non-motorized watercraft are also capable of transporting aquatic invasive species. The Tahoe Keepers program informs the paddling community about the importance of inspecting their equipment, keeping Kayaks, paddleboards, fishing equipment, inflatable water toys, and life jackets from spreading invasive species.

Carnelian Woods Townhouse Association Earns National Recognition for Wildfire Preparedness

Posted on

First Firewise USA® Community in the Lake Tahoe Basin

Years of efforts to reduce the vulnerability of homes and landscapes to wildfire has
earned Carnelian Woods Townhouse Association, Firewise USA® recognition status
from the National Fire Protection Association. Carnelian Woods completed a rigorous
set of criteria to become a participant in the national program.

  

“We are very proud that we’ve achieved the Firewise USA® designation. Reducing the
risk of wildfire can only be accomplished when we all work together,” said Celia Barry,
Carnelian Woods Board Member. She hopes that other communities in the Lake Tahoe
Basin will join the Firewise USA® program to help prevent wildfires in Lake Tahoe.

Tahoe Resource Conservation District’s Fire Adapted Communities Coordinator, Carlie
Murphy, illustrates the need for community outreach and education when working with
neighborhoods, “One of the most effective tools for bringing a neighborhood-wide
program into your community is ensuring there are plenty of opportunities for
individuals to ask questions and get involved in the process.” Murphy also emphasized
that there is no better time for neighborhoods to prepare for wildfire. Learn more about
what you can do to prepare for wildfire at tahoe.livingwithfire.info.

“Prepared, informed, engaged and proactive communities must take the responsibility to
mitigate their wildfire risk head-on, and understand that we all live, work and play in a
fire-dependent ecosystem. Communities must take responsibility, while working with
local Fire and Resource Conservation agencies, to help engage and inform community
members that it is imperative to work towards a common goal of meeting defensible
space requirements on all properties, as well as emphasizing the necessity of emergency
preparedness,” states North Tahoe Fire Protection District’s Defensible Space Inspector,
Eric Horntvedt.

Carnelian Woods worked with North Tahoe Fire Protection District and the Fire Adapted
Communities Program (through Tahoe Resource Conservation District) to complete a
community wildfire hazard assessment and develop an action plan that will guide their
efforts to reduce risks to residents and their homes. Implementation of their plan has
begun and will continue as part of the program’s annual renewal requirements.

Firewise USA® is a nationwide program that provides formal recognition to
communities implementing actions to protect people and properties from the risk of fire
in the wildland/urban interface. Participants reduce their wildfire risks by actively
participating in the program and completing requirements each year.
Communities interested in participating in the Firewise USA® program can learn more

Ten years of fighting aquatic invasive species at Lake Tahoe

Posted on

This year marks the tenth anniversary of Lake Tahoe’s Watercraft Inspection Program. Under the program, every motorized watercraft is inspected to ensure it is clean, drained, and dry and not carrying aquatic invasive species before launching at Tahoe. Thanks to diligent boaters and watercraft inspectors, no new aquatic invasive species have been detected in Lake Tahoe since the program began 10 years ago.

Of the nearly 8,000 vessels watercraft inspectors examined this boating season, 44 percent of them arrived clean, drained, and dry. Eleven watercraft were found carrying invasive mussels and 40 were harboring other species.

Adult quagga mussels were found attached to a personal watercraft at the Spooner roadside inspection station on July 18, 2018.

This exemplifies the excellent work by the inspectors, but also that watercraft continue to be a vector of aquatic invasive species. Each fouled vessel was decontaminated prior to launching in Lake Tahoe. The largest number of decontaminations occur on vessels containing standing water, which may contain unwanted seeds, plant fragments, or microscopic larvae.

Boaters are encouraged to continue to be a part of the solution by cleaning, draining, and drying their vessel before launching in any waterbody. This includes both motorized and non-motorized watercraft.

This July, Tahoe Resource Conservation District (Tahoe RCD) watercraft inspectors intercepted a pontoon boat harboring multiple aquatic invasive species of concern. An inconspicuous crack in the pontoon allowed water and vegetation to enter, and several invasive species then grew within.

 

The boat came from Eastern United States and was inspected at the Alpine Meadows watercraft inspection station on Highway 89 in California. Staff discovered standing water, adult quagga and zebra mussels, aquatic vegetation, New Zealand mudsnails, and multiple other species inside the pontoon system. After discovery of the invasive species, inspectors coordinated with California Department of Fish and Wildlife and performed a full decontamination of the vessel to kill and remove all invasive species.

On July 18, 2018, the adult quagga mussels were found on the reverse bucket of a personal watercraft.

“This incident is the perfect example of how boats are the number one transport mechanism for aquatic invasive species,” said Christopher Kilian, program manager at the Tahoe RCD. “This is a good reminder that you could unknowingly transport invasive species and highlights the importance of being diligent when practicing Clean, Drain, and Dry techniques before travelling to a new location.”

“They may hide on the hull, in your bilge, on your anchor, in your ballast system, or in this case: inside a pontoon. We’d like everyone to keep this in mind as they travel to other waterbodies or prepare for inspections.” All watercraft are required to be inspected prior to launching in Lake Tahoe.

 

Quagga mussels were found on board a boat at the Meyers roadside inspection station on August 22, 2018. The decontamination process included a hot water wash (140 degrees Fahrenheit) of all toys, life jackets, anchors and lines.

 

As fall approaches, boat inspections will move to select launch ramps and winter hours will begin on October 1.  Tahoe Resource Conservation District (Tahoe RCD) inspectors will be stationed at Cave Rock and Lake Forest boat launch ramps from 6 a.m. to 4 p.m. seven days a week, weather permitting. All boats without an intact Tahoe inspection seal are required to get an inspection during daylight hours.

Decontaminations are available at Cave Rock and Lake Forest throughout October as weather permits. Decontamination fees will apply for watercraft that are not clean, drained and dry. Watercraft that has been in a known infested waterbody will require a precautionary decontamination at no cost regardless of whether it has been cleaned, drained, and dry. Boats with intact inspection seals are permitted to launch at all open launch facilities; however, inspections are only available at Cave Rock and Lake Forest boat launch ramps.  Boaters are encouraged to confirm hours and inspection locations at TahoeBoatInspections.com or by calling 888-824-6267.

A new invasive species introduction in Lake Tahoe could have devastating impacts. Without natural predators, invasive species multiply quickly and can colonize the lake, as well as docks, water pipes, filtration systems, piers, ramps, and boats. They destroy fish habitat, impair boat engines, and negatively impact water quality and recreation, thus posing serious threats to the ecology, recreation, infrastructure, and economy of the Lake Tahoe Basin.

TNFAC: Helping residents and visitors prepare for wildfire

Posted on

Wildfires have been raging through the United Sates in 2018, with California having its worst fire year in over 10 years and Nevada currently recovering from the largest single fire in its history. With increased temperatures, low humidity, and large fuel loads of dead shrubs, brush, and trees left behind from the 2012-2017 drought, it is crucial to prepare now, before the next wildfire occurs.

To help residents and visitors in the Lake Tahoe Basin prepare for wildfire, the Tahoe Fire and Fuels Team (TFFT) created the Tahoe Network of Fire Adapted Communities (TNFAC). TNFAC is a multi-agency collaboration, led by the Tahoe Resource Conservation District, that brings communities together with the resources they need to prepare for wildfire. In wildfire-prone areas, fire adapted communities reduce the potential for loss of human life and injury, minimize damage to homes and infrastructure, and reduce firefighting costs by taking the necessary steps to prepare properties and people before a wildfire occurs.

Five steps you can take today to prepare for wildfire: 

  1. Access: Ensure your home can be easily accessed by emergency first responders during a wildfire by making sure your address is clearly visible from the street and any gated driveways can be accessed during an emergency. Contact your local fire district to ask if emergency first responders could arrive at your home in a safe and timely manner.

  2. Built Environment: Use fire-resistant or noncombustible materials on the exterior of your home, such as roofing, siding, decking, trim, windows, and fencing. Check for weak spots on your home where wildfire embers could ignite the structure and remove debris year-round from gutters, roofs, vents, and chimneys.

  3. Community Protection: TFFT partners work together to provide community protection to neighborhoods by creating fuel breaks on public land, utilizing prescribed fire, and implementing strategies from the 2015 Lake Tahoe Basin Community Wildfire Protection Plan. Help the TFFT by reducing fuels for wildfire on your property and developing fire adapted communities in your neighborhood.

  5. Evacuation: Sign up to receive emergency notifications, prepare an evacuation supply kit, develop a family emergency plan, and practice preparing your home, family, and guests for an evacuation. Sign up to receive emergency notifications to your cell phone, home phone, and email through your county’s emergency notification system:
    • El Dorado County: ready.edso.org
    • Placer County: placer-alert.org
    • Douglas County: douglascounty.onthealert.com
    • Washoe County: washoecounty.us/em/RegionalAlerts.php

The Fire Adapted Communities Program relies heavily on self-identified leaders to help organize their neighborhoods. Neighborhood leaders work with fire district personnel and the TNFAC to help distribute educational materials, plan community work days and wildfire preparedness block parties, and help keep wildfire preparedness on the neighborhood’s agenda year-round. If you or someone you know is interested in learning more about becoming a neighborhood leader, contact Carlie Teague at cteague@tahoercd.org or 530-543-1501 ext. 114.

The Tahoe Network of Fire Adapted Communities (TNFAC) participates in numerous community events around Lake Tahoe. Find out where TNFAC is next by visiting the events calendar at tahoe.livingwithfire.info/calendar/ or sign up for the monthly TNFAC e-newsletter.
